Comment #1 on issue 3646 by [email protected]: Weird solution of x**y =
0
http://code.google.com/p/sympy/issues/detail?id=3646
That's because of the indeterminate form 0**inf, I think. That will happen
if y is 0. Also, this may be because of the way the result is evaluated
symbolically.
I believe the result returned is correct because we have not explicitly
mentioned anywhere that y is non zero.
But then again, if we do mention that y is indeed non zero,
y = Symbol('y', nonzero=True)
solve(x**y)
[{x: 0**(1/y)}]
So, SymPy is returning the wrong result even when y is zero.
Anyway, I'll take a look into this.
